WebTriflate anion In organic chemistry, triflate(systematic name: trifluoromethanesulfonate), is a functional groupwith the formulaR−OSO2CF3and structureR−O−S(=O)2−CF3. The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO2CF3. For example, n-butyltriflate can be written as CH3CH2CH2CH2OTf. WebThis research provides a path for the development of more durable AEM electrolyzers with components that can minimize the adverse impact induced by the phenyl group oxidation, such as the development of novel ionomers with fewer phenyl moieties or catalysts with less phenyl-adsorbing character.
